 — The mining industry has seen several significant dam failures in recent years. Dam failures are associated with errors in design, implementation, operation, and monitoring (Azam, 2014, [2]).Dewatered stockpiling (dry stacking) is a safer alternative to tailings dams (Rico et al., 2008, [3]) for tailings disposal; however, this method has not …

The ore is a high grade, and high specific gravity magnetite ore with typically 65%+ Fe content. The specific gravity of the ore ranges from 4.5 to 5.1, making the ore suitable for both the steel market as well as the non-steel market. DFL processes this ore as iron ore fine and lump using dry screening and dry magnetic separation processes.
